Transparent routing in a power line carrier network

Meter nodes in a power line carrier (PLC) network may reliably communicate with an access point by alternate routes using additional media where available. A utility network may include one or more subnetworks. Each subnetwork may include one or more meter nodes and an access point configured to communicate with the meter nodes using PLC. Meter nodes operate as relays for other meter nodes to communicate with the access point. Some or all meter nodes may be configured to communicate using a power line carrier communications link and another communications link. The network may also include a node external to the subnetwork, e.g., a utility server. The access point may be configured to communicate with the node external to the subnetwork in addition to the meter nodes.
